As Cuomo pointed out, Trump had once dismissed former President Bill Clinton's scandal as unimportant, but is now bringing it up as a campaign issue.

"Leadership's about consistency. You said it in your book, 'The Art of the Deal,'" Cuomo told Trump during an interview.

Trump insisted that as a "businessman," he would give supporting statements to politicians like Clinton and his wife, former Secretary of State Hillary Clinton.

But after Clinton, now the Democratic presidential front-runner, said last month that Trump had generally displayed a "penchant for sexism," Trump started attacking her husband's sexual-misconduct allegations. Among other things, Trump declared that the former president had a "terrible record of women abuse."

Trump further told Cuomo on Monday morning that Hillary Clinton was an "enabler."

"I don't really care about Monica Lewinsky other than I think that Hillary was an enabler and a lot of things happening that were obviously very seedy," Trump said. "I mean, he was impeached, for heaven's sake! He was impeached over this stuff."

Cuomo noted that though Clinton was impeached by the House on perjury and other charges related to the scandal, he was subsequently acquitted by the Senate. But Trump — whose own sex life was splashed across tabloid front pages in the 90s — didn't back down.

"He was impeached. He paid a massive fine on one of the cases — like a massive fine. I think his law degree was even taken away — wasn't able to practice law. So obviously it was a big thing," Trump said.

"As a businessman, I would always stick up for various people, whether they were or friends or not, because in many cases I needed them," he continued. "I need their votes to get things done."
